MetaWeblog.ashx Error

I am trying to configure Windows Live Writer to work with EBE, but I get the following error. The response to the blogger.getUserBlogs method received from the weblog server was invalid. When I attempt to access the page directly I get "The
file you are attempting to save or retrieve has been blocked from this Web site by the server administrators." Does anyone have any suggestion on where I should start checking?

I reviewed the installation document and confirmed the folders under the Template features and Layouts exist and the CKS.EBE, HtmlAgilityPack and Mvp.Xml dll are in the GAC. When I look at the web.config I do not see reference to a handler? Forms
Authentication appears to be working correctly.

When setting up Windows Live Writer I select Another Weblog Service then Metaweblog API and enter https://servername/metaweblog.ashx. <-- My Blog is setup at the root.
